Posted on August 01, 2017 at 16:03Hi ForumI'm trying to implement USART Rx of variable, unknown length messages at a 1Mbps baud rate through DMA. I would like to minimize the latency from receiving to consuming the data, so I'm trying to do this wit...
Hi , I encountered an interesting problem while I was trying to calculate the Bit-Banding Address of GPIO registers .The peripherals working on AHB2 and AHB3 busses are overflowing when trying to calculate their bit-banding map .. For Example ;I wan...
Hi,It says on page 107 of stm32f777bit6 manual that:"Each OTP data block can be programmed until the value 0x00 is programmed in the corresponding OTP lock byte."I understand that OTP is supposed to be one time programmable but the above statement se...
There is the Figure 80 "DMAMUX block diagram" in the STM32F743 Reference Manual (RM0433), which shows that there is 'm' number of dmamux_evt signals, where 'm' is 16 for DMAMUX1 (the number of DMAMUX1_CmCR channels).The Manual only describes the dest...
HAL_I2C_Mem_Read(I2C_HandleTypeDef, Address, REGUSTER, rsz, buff, bsz, tout);If the device address is 0x77,what is th proper way. I can find non consistent answers, though i cannot read. I get HAL_ERORis it:Anyway each option returns non consistent d...
Hi,I suspect that I encountered with undocumented silicon error of STM32L432KC, while I'm playing with a Nucleo32-L432KC board. Here is how to reproduce it:Start a new project with CubeMX v.4.27.0Select SPI1 as a full duplex master(PA1:SCK, PA6:MISO,...
Is there a way to retrieve the value APBx timer clocks are set to?I have found functions to get the PCLK1 and PCLK2 frequencies but there is a multiplier that can change the final timer clock so that is not reliable.
I am able to receive only 0x0D in receive buffer, but I can see different data in Receive string.Please can someone help me..unsigned char i = 0, k = 0; //HAL_GPIO_WritePin(GPIOC, GPIO_PIN_2, GPIO_PIN_SET); //Switch ON GSM LDO __HAL_UART_ENABLE_IT(&h...
