I need to integrate an STM32G071RBT into an existing design with a parallel bidirectional data bus. Based on section 7.3.10 of RM0444, I believe I should be able to do this by configuring my GPIO as open drain. In this configuration, if an external...

I am designing a board and would like to use the 32 bit timer (TIM2) in encoder mode. Per the block diagram in RM0444:the inputs to the encoder interface are T1FP1 and TI2FP2, which originate from TIM2_CH1 and TIM2_CH2 (highlighted in yellow). It a...

Referring to RM0444 and DS12232 (referring to STM32G0x1 programming manual and data sheet).In the Low Power section, the RM states that there are five wakeup pins:But in the register section, there is clear mention of WKUP3 (EWUP3 bit in PWR->CR3, WP...

I have configured my STM32G071 SPI peripheral to transmit 8 bits with the following code:void spi_config(void) { RCC->APBENR2 |= RCC_APBENR2_SPI1EN; //Enable SPI Clock   //Configure for SPI mode (not I2S mode) SPI1->I2SCFGR &= ~SPI_I2SCFGR_I2...

I am attempting to write register level code to control the I2C peripheral in an STM32G0x1.My read function is failing because the RXNE bit is never getting set. I believe I have implemented the state machine described in RM0444 (p. 958). Is there ...
