Posted on October 09, 2016 at 09:45I'm getting a basic compile error in stm32f4xx_hal_i2c.c. The header on the file says:   * @file    stm32f4xx_hal_i2c.c   * @author  MCD Application Team   * @version V1.5.1   * @date    01-July-2016 I see: HAL_Sta...

Posted on June 14, 2016 at 11:10I notice that the HAL locates some lookup tables in RAM. For example, in stm32f1xx_hal_rcc.c:uint32_t HAL_RCC_GetSysClockFreq(void) { &sharpif   defined(RCC_CFGR2_PREDIV1SRC)   const uint8_t aPLLMULFactorTable[14] = {...

Posted on June 10, 2016 at 17:23The purpose of this post is to save other developers the time I have spent tracking this down. Bear with me on this - its messy. Line 1108, of stm32f1xx_hal_rcc.c is  if (pllmul == aPLLMULFactorTable[(uint32_t)(RCC_...

Posted on May 06, 2016 at 16:14Short question: What is the recommended way to implement a bi-directional data bus on STM32 using the HAL? Longer version: Our code needs to interface to a LCD controller over a 8-bit bi-directional bus. To do this, we...
