Posted on April 13, 2017 at 16:41Hello.Can anyone help me with CAN filters configurationI need to implement 3 independent cases of the filters(will be used independently, so not in same time)Case 1 (for OBDII 11 bits communication)I need to receive ...
Posted on April 13, 2017 at 06:44Dear Sir, I m using timer1 of STM32F407 to get Edge-aligned PWM & using the following settings to give 84 MHz clock to timer1 :RCC->PLLCFGR &= ~(0x1F); //PLLM=0 RCC->PLLCFGR |= 0x08; //PLLM=8 RCC->P...

Posted on April 12, 2017 at 19:23HiI am implementing a USART driver and would like to use DMA for reception. In order to detect a timeout on the RX line, I use the USART idle interrupt.The DMA works and I receive the expected characters. However onc...
Posted on April 13, 2017 at 07:49It is: https://nettigo.eu/products/power-supply-apv-35-5-mean-well-5v-5-0a, like the text says, APV-35-5 MEAN WELL 5V 5.0A. It is dedicated for LED lightning, but will work with STM32 / Nucleo, yes?I will get 4A from...
Posted on April 12, 2017 at 02:50Hi All,Which flag in the UART DMA can be checked to indicate that I received a new byte. I also would like to check the DMA of my UART while its receiving, and if I receive a special character say '\r',I want to star...
Posted on April 08, 2017 at 15:31Hi,Have been doing quite a bit of drawing onto a LCD display with SPI and DMA. In the process of updating the display, i found the results were unexpected, but the code doesnt seem to be the culprit, since when I tes...
Posted on April 12, 2017 at 12:53I will be designing a custom board for STM32L053C8T6 Controller . And also i want to include a ON board programmer /dubugger by using STM32F103C8T6 chip . So my question is do i need to program STM32F103C8T6 chip to...
