Posted on August 30, 2017 at 13:05 I recently noticed a strange case on STM32F7 I measure the execution time of this function by clock cycles. which is just a simple while loop. void LK_ADDr(float *im, float *meanParameter, int Size ) { ...
Posted on June 23, 2017 at 17:49Hello,I start a project with STM32CubeMX and a NUCLEO-F207ZG board. My goal is to have a TFTP client, but for now I'm stuck getting an IP address with DHCP. You can find my project attached.In the lwip.c, I had to mod...
Posted on August 30, 2017 at 15:46Hello Community,I work on a STM32L151CCU6 and I need your help.I try to measure VDDA voltage in order to calculate a voltage divider on PA2 (single mode). My two ADC configuration functions are :void MX_ADC_Init(voi...
Posted on July 31, 2017 at 20:49Hello all,I have created a new PCB with a STM32F746ZG chip but the issue is that I am able to upload the GPIO IO Toggle example from the NucleoF746 folder but the LEDs do not blink after uploading. I have tried making...
Posted on August 31, 2017 at 00:52Hi Everyone,I've been evaluating an SPWF01SC to see whether it's suitable to add web browser file transfer functionality and a control interface to an existing embedded (bare metal) project.Host controller is an STM...
Posted on August 30, 2017 at 21:03I'm debugging a new board which uses the STM32L496QEI6 and found that the HSI and MSI clocks are running about 8% too slow which is way outside the specification. (This error shows up both on both the UART pins and ...
Posted on August 30, 2017 at 23:09Hi,I'd like to know if it is possible to configure alpha blending such that the transparent pixels of a child rectangle are blended with the frame buffer contents created by the parent. It appears the only way to b...
Posted on October 29, 2016 at 17:48having a frustrating time with the new utilities, using an STM32F103RBT6 repeatedly getting a ''fail to save bin/hex'' type error when using ''Save As''. Didn't seem dependent on file name, and file name didn't cla...
Posted on August 29, 2017 at 00:01This is the section of code I think needs changed in HAL_USART_Transmit(...);if(husart->Init.WordLength == USART_WORDLENGTH_9B) ....else { if(USART_WaitOnFlagUntilTimeout(husart, USART_FLAG_TXE, RESET, tickstart, T...
