Posted on April 26, 2016 at 12:25Hi, I am using the STM32F429ZI CAN peripheral in polling TX and interrupt RX with HAL library V1.4.4 of 22-January-2016. This the procedure that I use: During CAN init, I call the HAL_CAN_Receive_IT to enable the f...
Posted on April 26, 2016 at 11:25Hi all,I am working with STM32F411CE. I know that if I use below code will occurred every 1 ms, but it occurred every 0.5ms in my code. HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq()/1000); // HAL_RCC_GetHCLKFreq = 9600...
Posted on April 26, 2016 at 10:50I made code with the STMCubeMX. It has several ADC channels enabled. I have read the stm32f4xx_hal_adc.c file and others through, but I can't find the channels in the code. How are more than one channels handled? I ...
Posted on April 25, 2016 at 16:22I, I'm using Altium designer and I'm rooting a UFBGA64 (STM32F098RC). BGA pad dimensions are the following:Pitch: 0.5mm/Dpad:0.280/Dsm 0.370mm. I would like to know what is the best solution to place vias for this UF...
Posted on April 26, 2016 at 11:01Hi all, I am having an issue with USART behaviour and am wondering if any of you can help! I am using an STM32F303 with three of its USARTs in use, of which USART1 is configured as an asynchronous RS485 port with its...
