سلام
با SPI کار کنم بهتره
جواب سوال هام رو که نمیدید
پس این یه صحفه متن رو ترجمه کنید
6.3. SPI serial interface
SPI synchronous serial interface signal lines include: SPI chip select input pin SCS, serial clock input
pins SCK, serial data input pin SDI, serial data output pin SDO and interface busy status output pin BZ.
Through SPI serial interface, CH376 can use less connection to connect to a variety of MCU, DSP, SPI
serial bus of MCU, or a more long-range point to point connection.
SCS pin of CH376 is driven by SPI chip select output pin or common output pins of MCU, SCK pin is
driven by SPI clock output pin SCK of MCU, SDI pin driven by SPI data output pin SDO or MISO of MCU,
SDO pin is connect to the SPI data input pin SDI or MISO of MCU. For SPI hardware interface,
recommended SPI setting is CPOL = CPHA = 0 or CPOL = CPHA = 1, and the data bit sequence is high in
the front MSB first. SPI interface of CH376 also supports MCU common I/O pin simulate SPI interface to
communication.
If INT # pin do not connect, you can get interrupt by query SDO pin, the method is let SDO pin
exclusive one of MCU input pins, and through CMD_SET_SDO_INT command sets SDO pin do interrupt
request output when the SCS chip select valid.
SPI interface of CH376 supports SPI Mode 0 and SPI Mode 3, CH376 always input data from the SPI
clock SCK rising edge, and output data when allows output from the SCK falling edge, data bit order is high
in the former, counted 8 bits as a byte.
The operation steps of SPI are:
① MCU generate SPI chip select to CH376, active with low-level;
② MCU sends a byte data according to SPI output mode, CH376 always received the first byte after
SPI chip select SCS effective as a command code, the follow bytes as data;
③ SCM inquiry BZ pin waiting for SPI interface of CH376 is free, or directly delay TSC time (about
1.5uS);
④ If the write operation, MCU send to CH376 a byte data to be written, waiting for SPI interface is
free, MCU continues to send a number of bytes data to be written, CH376 receive in turn, until MCU forbid
SPI Chip Select;
⑤ If the read operation, MCU receive a byte of data from CH376, waiting for SPI interface is free,
MCU continues to receive a number of bytes data from CH376, until MCU forbid SPI Chip Select;
⑥ MCU forbid SPI Chip Select, to end the current SPI operation.
The following figure is the SPI interface logic timing diagram, the former one is to send command 12H
and write data 34H, the latter one is to send command 28H and read data 78H.

اگه این صحفه رو ترجمه کنید فکر کنم دیگه کارم راه بیفته

اولش که قصه میگه

بعدش

For SPI hardware interface,
recommended SPI setting is CPOL = CPHA = 0 or CPOL = CPHA = 1, and the data bit sequence is high in
the front MSB first. SPI interface of CH376 also supports MCU common I/O pin simulate SPI interface to

یعنی شما باید spi رو تو مد CPOL = CPHA = 0 or CPOL = CPHA = 1 قرار بدید.
بعدش

The operation steps of SPI are:
① MCU generate SPI chip select to CH376, active with low-level;
② MCU sends a byte data according to SPI output mode, CH376 always received the first byte after
SPI chip select SCS effective as a command code, the follow bytes as data;
③ SCM inquiry BZ pin waiting for SPI interface of CH376 is free, or directly delay TSC time (about

④ If the write operation, MCU send to CH376 a byte data to be written, waiting for SPI interface is

SPI Chip Select;
⑤ If the read operation, MCU receive a byte of data from CH376, waiting for SPI interface is free,
MCU continues to receive a number of bytes data from CH376, until MCU forbid SPI Chip Select;
⑥ MCU forbid SPI Chip Select, to end the current SPI operation.

یعنی برای کار شش مرحله داری یا شش نکته بگم بهتره.
1. قبل از هر کاری mcu که میکرو باشه باید پایه cs رو صفر کنه تا فعال بشه.
2. بعد از اون اولین بایتی که میفرسته به منزله دستور مورد نظر تلق میشه که باید به جدول دستورات مراجعه کنی.
3. بعد حدود 1.5 میکرو ثانیه طول میکشه تا دستور پردازش بشه و باید delay بدی.
4. اگه دستورت خوندنیه ، یعنی تو این دستور باید یه چیزی رو الان از آی سی بگیری خوب باید با توجه به دستورت که چی باشی صبر کنی آی سی کارش تموم شه و بعد دوباره ازش بخونی هر چند تا که لازمه و بعدش cs رو یک کنی.
5. اگه دستورت نوشتنیه باز هم باید بنویسی و در نهایت cs رو یک کنی که به آی سی حالی کنی تموم شد.
6. اگه دستورت هیچ کدوم از دو حالت بالا نباشه، یعنی نه منتظری که چیزی بگیری از آی سی و نه میخوای بفرستی خوب باز هم باید cs رو 1 کنی که آی سی کار اجرای دستور رو شروع کنه.

من هم برنامه ای که نوشتم و ظرفیت فلش و مقدار خالیش رو میده میزارم شاید به درد کسی خورد. شما که بسکام کار میکنی

پاسخ : فرستادن یه کد مثل 03H به یه ای سی یا ...

با تشکر از پاسختون
یعنی فقط باید سیم های MOSI MISO SCK CS رو وصل کنم با VCC و GND هم 6 تا سیم میشه ؟
این CS که برای رم SD هست ؟
SCS همون CS که شما گفتی هست ؟ اگه این همون باشه جواب سوال بالایی رو نمی خواد دیگه
پروتکل SPI باود هم نداره با هر سرعتی میشه کار کرد ؟
اون شکل پاین همن نوشته توی دیتاشت می خواست همینو بگه ؟ صحفه 21
در مورد SMD به DIP هم شنبه میرم میدم بیرون درست کنه ؟ تونستم درست کنم اما موقع سوراخ کردن خراب شد :mrgreen:
باز هم تشکر می کنم ممنون

6.4. Asynchronous serial port
CH376 serial asynchronous serial data format is not compatible with CH375, and does not support
external firmware USB device mode.
Asynchronous serial signal line includes: serial data input pin RXD and serial data output pin TXD.
Through the serial interface, CH376 and MCU, DSP can be a more long-distance connection with the
least connection.
RXD and TXD of CH376 can be connected to the MCU serial data output pin and serial data input pin
respectively.
CH376 serial data format is the standard byte transmission mode, include 1 start bit, 8 data bits, 1 stop
bit.
CH376 supports both hardware-set the default serial communication baud rate, also supports MCU
select the appropriate communication baud rate at any time by CMD_SET_BAUDRATE command. Every
time after power-on reset, CH376 default serial communication baud rate is set by BZ/D4, SCK/D5, SDI/D6
three pin power level combination, refer to the following table (in the table 0 denote low-level , 1 denote
high-level or un-connection).

In order to distinguish between command code and data, CH376 asked MCU through the serial port to
send two synchronization code bytes (57H and ABH), and then send command code, follow send data or
receiving data. CH376 will check time interval between the two synchronization code, synchronization code
and command code. If the time interval is greater than serial input timeout SER_CMD_TIMEOUT (about
32mS), then CH376 will discard the synchronization code and command package. Serial command operation
steps are as follows:
① MCU send CH376 the first synchronization code 57H through serial port;
② MCU send the second synchronous code 0ABH to CH376;
③ MCU send command code to CH376;
④ If this command have input data, then send CH376 input data in turn, one byte one time;
⑤ If this command have output data, then receive output data from CH376 in turn, e one byte one time;
⑥ Command complete, some commands generate interrupt message after execute complete and send
interrupt state code through serial port, MCU can suspended or turn to step ① to continue executing the
next command.

6. Functions Description
6.1 MCU Communication Interface
It supports three kinds of communication interface between CH376 and MCU: 8-bit parallel interface,
SPI synchronous serial interface, UART interface. When chip power-on reset, CH376 will sample WR#,
RD#, PCS#, A0, RXD, TXD pin state, according to the configuration state of these pins combination
selection communication interface, consult to the following table (in the table X denote not care about this
bit, 0 denote low-level, 1 denote high-level or un-connection).

There are two communication interfaces between CH376T and MCU: SPI synchronous serial interface,
UART interface. When chip power-on reset, CH376T will sample SPI state, when SPI# is low-level, select
SPI interface, SPI# is high-level select UART interface.
INT# pin of CH376 output interrupt request is active with low-level in default, it can be connected
to the MCU interrupt input pin or common input pin, MCU can get interrupt request of CH376 by using
interrupt mode or query mode. To save pins, MCU can not connect to INT# pin of CH376, but get interrupt
by other ways.
