Hello,I created UDP server with LwIP stack on STM32F407.I tried example udp_echo _server. It works.Now I need send from server my own answer data in callback function.The program hangs in callback function.void udp_echoserver_receive_callback(void *a...
Hi there. I am testing my circuit with a 3.3V sine wave that has a 1.65V DC offset. PC01 has the Signal InputPC02 has the 1.65V.Looking at the output file from the ADC, I am not getting the total signal. 0-4096. My wave is between 1000 and 3000 appro...
Hi,I'm getting a problem in my project, where I tried to create a loopback between I2S3 and I2S4 on STM32F411 Disco.It seems that only the least significant bit of 16-bit packets is somehow shifted to the next packet. The rest of the transmission is ...
Hello,another day, another N6 "issue" :)I want to do RAM to RAM copy by HPDMA, but the data never get copied from Src to Dest, Dest always stays unmodified. I have checked the 'DMA_RAMToRAM' example for N6 and went from there, but with no success.DMA...
Configuring SPI for 24 bit data frames and receiving single data frames via HAL_SPI_Receive_IT (which redirects to HAL_SPI_TransmitReceive_IT() in case bidirectional transfer is enabled), hspi->RxXferCount and hspi->RxXferSize are both set to the val...
Hi guys, im initializing a low/ultra low power project and i will use the STM32C011J4M6, i need to know if a general purpose timer like the TIM14 can wakeup the microcontroller in the low power modes (sleep, stop, etc).I was reading the datasheet (i ...
@Tesla DeLorean Hi! Thank you for helping me with the BOOTING process. However, I have a question about the peripherals. I am planning to control a TFT screen that requires 40 pins and RGB protocol. At first, I was planning to choose random GPIOs to ...
Hello, I have further questions related to ADC1 and MDF. The solution solved this case: ADC1 with one single input channel. How about multiple input channels are connected to ADC1 of STM32U585? I use 4x analog inputs as example, they are connected ...
Hi,I notice in the STM32H747XIH6 reference manual (RM0399) that "During and just after reset, the alternate functions are not active and most of the I/O portsare configured in analog mode." I want to confirm that in "analog mode" the IO is an HZ inpu...
IN AN4899, figure 18, it states:"To reduce power consumption, setthe pin as a push-pull output anddrive it in the same direction as theinternal pull-up / pull-down resistor.Alternately, set pin as analog input."I'm a little confused here. If there is...
