I have updated my SDK,but issue still exist, can you tell me what bug with "There was a bug with spi clock before"? At the moment I found that DMA can not be sent and transmitted at the same time.ESP_Sprite Posts: 9814 Joined: Thu Nov 26, 2015 4:08 am Re: spi trans bug...
检查与SPI设备通信相关的代码: 审查涉及SPI通信的代码部分,特别是与设备句柄相关的操作。 确保在调用SPI通信函数之前,已经正确获取了设备句柄。验证设备句柄是否在使用前已正确初始化: 在使用设备句柄之前,确保它已经被正确初始化。这通常涉及到打开SPI设备文件、配置SPI参数(如时钟频率、数据位、极性、相位等)等...

I am trying to read 3584 bytes from SPI, but I got "E (10547) spi_master: spi_device_queue_trans(782): txdata transfer > host maximum" and I don't know why. My SPI configuration is this: Code:Select all spi_bus_config_tspi_bus_cfg = { .mosi_io_num=MOSI_PIN, .miso_io_num...
Full-duplex SPI with cs_ena_pretransby DurandA » Mon Apr 27, 2020 11:01 am Hi! According to ESP-IDF documentation, using cs_ena_pretrans (https://docs.espressif.com/projects/esp ... _pretransE) only works on half-duplex transactions. However, my device works in full-duplex and ...
The data transfer works but I sometimes get duplicated repeated outputs on the PSoC which I don't see using a scope that can decode SPI. For example if I am sending 'DEAD BEEF' infinitely, I would get "DEAD BEEF DEAD BEEFDEAD DEADBEEF.." or "DEAD BEEF DEAD BEEF DEADBEEF BEEF..."...
The Montgomery Lake, Padlei and Spi successions are interpreted as being rift-related, and are older than the 2.1 Ga gabbro that intrudes the Hurwitz Group. Recognition of widespread rifting in this part of the Hearne Province constrains tectonic modelling of the preorogenic history of the ...
