Posted on July 27, 2017 at 11:55Hey guys,I have a function that parses messages of my own format and splits them into an opcode and (0-3) operands.With 0 or 1 operand, it works fine; on the second operand, the msg.substr(start, (pos - start)); cause...
Posted on July 27, 2017 at 13:23Hi,I communicate with ADS1299(24bit, 8CH ADC chip) by SPI.ADS1299 SPI specification isCPOL=0 CPHA= 1Max SCLK = 20MHzand command flow is1) send read command(0x12)2) send dummy(x00) to make SCLK and receive 27 byte data...
Posted on July 22, 2017 at 02:47I find when I make a call to HAL_I2C_Slave_Receive_IT it returns HAL_OK but it never manages to call the callback function, my HAL_I2C_SlaveRxCpltCallback(I2C_HandleTypeDef *I2cHandle) implementation.Using a logic ana...
Posted on July 27, 2017 at 11:48I got to know that STM32F407VGT6 has an internal RTC support with either internal oscillator or an external one. Since the internal 32kHz oscillator is not that accurate, I would like to use an external 32kHZ oscillat...
Posted on July 27, 2017 at 10:56Hi,I use stm32f745 processor and SDMMC (SD 4 bits Wide bus ) at CubeMx. While sd card is writing data at every one minute, sometimes code is stopping at SD_FindSCR function in stm32f7xx_hal_sd.c library. This event is...
Posted on July 24, 2017 at 10:29Hi,i already have done the setup for the lwip stack on the STM3210C-Eval board. I can already send via TCP/UDP and also RS232 to the uC (PC-->uC) and get also a echo back (uC-->PC). The debug output of the lwip-stack ...
Posted on October 05, 2016 at 23:30 I'm having trouble implementing the STM32CubeF4 CAN example on my STM32F429I-Disco board. I'm using the CAN Network example provided with the STM324x9_Eval which in the readme.txt says: This example runs on STM32F...
Posted on July 24, 2017 at 20:37Hello,The current version 2.8.0, and the pre-release version V2.9.0RC4 floating around in the forum, do not support the STM32F423 CPU. There is no map file for this CPU. Is there an updated pre-release of the program ...
Posted on July 26, 2017 at 03:40Data sheet for STM32F303 Vih specification indicates;1. TC and TTa I/O = 0.445*VDD + 0.3982. FT and FTf I/O = 0.5*VDD + 0.23. All I/Os except BOOT0 = 0.7*VDD. Item 3 seems to contradict 1 and 2. Can this be cla...
Posted on June 29, 2017 at 17:15The mantissa in USART_BRR is 12-bit i.e. its maximum value is 4095. That limits accordingly the minimum attainable baudrate for given APB frequency.The following values in example tables are thus invalid and those bau...
