Resolved! HAL_I2S_TxCpltCallback is called only once

I'm testing whether HAL_I2S_TxCpltCallback or HAL_I2S_TxHalfCpltCallback is called properly by setting i2s to normal and periodically calling HAL_I2S_Transmit_DMA. However, HAL_I2S_TxCpltCallback or HAL_I2S_TxHalfCpltCallback is called only once and ...

Problem with ST SPI on STM32L475.

Hello, I am using STM32L475 board and trying to communicate with VNF1048F by SPI. The communication protocol which is used is defined as ST-SPI. On STM32 I can configure at maximum 16 bit communication but the device (VNF1048F) requires 32-bit frame...

STM32 internal oscillator drift over time

I designed a board using a STM32L031F6P6 about 4 years ago,  (April 2021).   The design has been using the internal oscillator running at 16Mhz perfectly for years.   Then this past summer all of a sudden the RS232 Uart stopped receiving data until I...

SSI and Circular DMA

Hello!I am writing a driver for the mt6701ct rotary magnetic encoder, using cubeIDE and an stm32f405 MCU. This sensor communicates via SSI, which is to say that it's read-only (MISO-only; there is no physical connection to MOSI). Using a simple polli...
