I2C with repeated start.

I have seen the question asked many times, references made but the question never gets answered with precision.  So, once again...I want to use HAL_I2C_Master_Seq_Transmit_IT along with receive to read an I2C device register.1. START SLAVEADDRESSWR (...

Resolved! HAL_ADC_Start_DMA caused main loop to become blocked?

Hi, I am configuring the ADC in single-channel continuous conversion mode using DMA. However, once I call HAL_ADC_Start_DMA(&hadc, &AD_RES, 1), the main loop stops executing, and the HAL_ADC_ConvCpltCallback() function is not triggered.I noticed that...

Resolved! Minimum hardware requirements for STM32F765

Can anyone tell me or direct me to a source that shows the minimum connections needed to power up and serially program a STM32F765ZGT6? (144 pin package.) I will be attaching the chip to a breakout board and will be using a St-Link Minie3.  Any help ...

Resolved! OCTO SPI output impedance on H7-series

I have swapped from a custom PCB-board with a 6-layer stack using a STM32H725IGKB, to another custom board with a 4-layer stack using STM32H723ZGT6 (simpler package).I am using an external OCTO SPI on both boards, but I have R/W errors with the 4-lay...
