Posted on May 24, 2017 at 18:59Hi,I'm using an STM32F446.I use the circular DMA feature with a DAC output to generate a sinus waveform.My sinus buffer has 32 values.What I would like to do is :- run the DMA for a 'large' amount of time- be able to s...
Posted on May 24, 2017 at 14:37Hey guys,I'm using a serial terminal to communicate with USART3 on an STM32F1 via an FTDI USB-UART converter cable. I am successfully receiving data from USART3 in my serial terminal but when I try to send data to it t...
Posted on May 24, 2017 at 18:24For my design i am already using STM32F429BI--LQFP208 package, Now i am looking to replace this with STM32F777BI-LQFP208, both are pin compatible..Question: In the data sheet of STM32F777BI Its mentioned that GPIO'S=15...
Posted on May 25, 2017 at 08:47Hi, Generally i do likeOption 1)unsigned char tmp;unsigned char *ptr='Hello World!';for(tmp=0;tmp<10;tmp++){ HAL_UART_Transmit(&huart1,ptr,strlen(ptr),100); HAL_Delay(10); //10ms}Option 2)Start TIM2 ,which gener...
Posted on May 25, 2017 at 08:24If CHECKSUM run by SOFTWARE ethernet fritz in some packets (spam).//#define CHECKSUM_BY_HARDWARE in lwipopts.hEthHandle.Init.ChecksumMode = ETH_CHECKSUM_BY_SOFTWARE; in ethernetif.cHow can i fix it?
Posted on May 24, 2017 at 21:04I have two different boards that both use an STM32F303, same memory size, but one of our boards uses a VCT7 (100pin) and the other uses an RCT7 (64pin).I am looking for a way to tell if it is the 64pin opr the 100pin t...
Posted on May 23, 2017 at 18:02I dont know I must be wrong but I didn't find function call to change the dutycycle of a pwm so I wrote this and I added it to stm32F3xx_hal_tim.c/** * @brief Set the PWM DutyCycle. * @param htim: TIM handle * @pa...
Posted on May 22, 2017 at 15:35The STM32L471 Errata document states that: An overconsumption can appear on VDDA in the following conditions:• a voltage VPAD is applied on PA3 or PB0 with VDDA+ 50 mV < VPAD < VDDA + 600 mV ...Our application uses ...
Posted on May 22, 2017 at 14:13HI I want Receive characters from USART. I don't know how much characters will be sentand the data that will be sent is too much. in interrupt mode i will receive amount interrupts and it is not good(for example 1000 ...
