Posted on November 12, 2016 at 20:34Hello, you may remember STM32F2 and F4 had troubles with some HS-USB ULPI transceivers from Microchip. I wonder if these issues exist with STM32F7 too ? I'm especially interested in USB3317 and USB3343. I've notic...
Posted on November 17, 2016 at 12:16Hi guys, we have a IS42/45S16100H device connected to STM32 FMC bus ( BANK2 ). If we run the application from internal SRAM everything is fine. Unfortunately, if we use the SDRAM as heap, we have trouble. Someti...
Posted on November 17, 2016 at 18:26Why if i put a voltage equal to 1V to the ADC input of the microcontroller, i read a value equal to 1.4 V??It seems that the Voltage_Actual_Value=0.7*ADC_ValueThanks #more-facts #!stm32-!adc #please.
Posted on November 14, 2016 at 16:59Hi guys,I want to use the internal 8MHz HSI reference for generating my clocks, but allthough there is now clock speed error to resolve I still get an error that the HSI is not recommended for the PLL as input. Wh...
Posted on November 14, 2016 at 10:38Hi All,I have a custom hardware dev board which includes an SDRAM (AS4C16M16SA), NOR Flash (S29GL128S) and a STM32F429. The schematic for this board is identical to other commercial dev boards that have the same m...
Posted on November 16, 2016 at 01:19I am using STM32F411RET6 and RCT6 chips. For some reasons, I can't tell the chip number in the board because it is blocked by something else.Therefore I present all the chips are RCT6, which has a smaller code spa...
Posted on November 16, 2016 at 21:14I am looking to implement receivers for infrared remote control protocolsusing STM32F407 bord.However all my attempts failed. Anyone can help my write a simple code to read the sensor input ?? Appreciated , thank...
Posted on November 17, 2016 at 19:47Hello, today i received my Nucleo 64 STM32L476 Board. When i make a new Keil project with only SPI (without DMA) and generate and open the project i got an error while building the project: *** Scatter Error: no d...
Posted on November 17, 2016 at 20:02I'm on an STM32F4 and using an RTOS. I put the MCU to sleep whenever the scheduler has nothing to do using the WFI instruction. I'm using DMA1 with i2S and a USART. I want to disable the DMA1 clock using the RC...
Posted on November 17, 2016 at 18:22 Hello In stm32L1 Cube lib 1.6. In the interrupt handling of a transfer complete on i2c in slave mode with DMA, the HAL_DMA_IRQHandler(...) calls XferCpltCallback(...) which points to I...
