Here are the logs and waveforms. The slave device of IIC is unable to raise the SCL response. The data cannot be sent out either. The code is provided in the attachment.HAL_I2C_AddrCallback: 开始接收数据接收到字节[0]: 0x40接收到字节[1]: 0x03接收到字节[2]: 0x22接收到字节[3]: 0...
Hello everyone, I have a custom PCB with an RFM69HCW and an STM32L011G4U6, I'm stuck, transmission and reception work fine, but if I want to add an ID, it gets stuck, here are my two INI files, sorry for my English. void RFM69_Init_RX(void) { uar...
Cross-posting from CC1125 Sleep current rises to ~2mA on the TI forum.I have a custom board with STM32F030 controlling a TI CC1125 sub-GHz radio transceiver via SPI plus a few GPIOs.Everything is fine for normal operation (TX, RX, etc), but the syste...
Hello, I have implemented a DDS sine wave generator where I use a timer interrupt to update DDS phase word and also use the same timer triggering a SPI transmission via DMA to an external DAC using a nucleo-g431rb. I am now doing the same thing with ...
Hello, I want to cancel my attendance to one of the online workshops as I won't be able to attend, by I can't find any contact information or procedure to do it.
Hi all,I'm looking for recommendations on eMMC chips that are known to work reliably with the STM32H743 via SDMMC1 in 8-bit mode.I've gone through a number of threads here and put together what I've found so far:- Micron 4GB (MTFC4GACAJCN) — comes up...
The STM32F415 transmit and receive lines are connected to the MAX3232 chip. The board also contains chips to control LEDs and read tokens, which are controlled by the STM32F415, and those functionalities work, but I am having issues with the RS-232 c...
I am trying to interface STM32L432KCU6 with ADIN1110. Volktek IMC-553 media converter is used to bridge the MCU board with laptop. I am trying to send UDP data. But communication is not succesful. I have a custom project board with the MCU as well as...
Hello ST Community,@pavel_A@erwan_CI am working on a project using STM32 NUCLEO-F446RE and the SmartElex Power Meter (ACS37800) for voltage, current, and power measurement over I²C.https://robu.in/product/1-month-warranty-1276/?gad_source=1&gad_campa...
I am creating a commercial educational course for the STM32F103C8T6 microcontroller.My planned usage:Taking static screenshots of specific datasheet pages (register tables, timing diagrams, memory maps)NOT showing the entire datasheet — only essentia...
