Hi everyone,I have a stm32f746 discovery board and I want to configure a snmp agent on it. I followed a simple example and wrote a code. In my code, I want to send a constant value in snmp protocol when i call its OID. I test my code using "Paessler ...
I used USART interrupt for RS485 encoder communication. I send 8 bit data and encoder reply with a 16 bit data. The first 8 bits out of 16 bits are received correctly. But second 8 bits didn't get correctly. I observed receiving data using oscill...
Dear all,This is supposed to be simple, but I have a serious problem that left me no choice but ask for a help! So any contribution is appreciated =) I have interfaced a STM32F103RET6 with an external 7614e DAC using SPI. According to the DAC datas...
Hello Every BodyDoes any one have any code for setting up Wifi with sdio?My micro is STMF412 and My wifi module is JC-TSM89ES (Realtek RTL8189ES) Single Module.
Hi there,First of all, thank you for reading this post. I have a system that has an ARM Cortex M4 MCU interfacing with STM32G4 via SPI. In the current design, STM32G4 takes care of motor commutation related tasks. So the question I have is that who s...
Hi. I'm trying to develop a kind of DSP for voice processing and I decided to do a bypass application first. I'm simulating my project with proteus and STMF103T6 device. As this device haven't DAC, I need to use a external 12 bits - DAC, and I did pr...
I've read in RM that, when running on 64 MHz it has 2 wait states, meaning that 1 cycle instructions execution takes actually 3 cycles. If I understand this correctly, that means that the effective speed is actually 21.3 MHz? What use is there using ...
Hello,I just started with a Nucleo F439ZI and did some tests to examine interrupt latency and code execution times. Here are my results and a number of questions:I set the system to the maximum speed using CubeMX, so I have HCLK and FCLK = 180MHz, AP...
Hi, guys.Here is short description of my project:I have an ADC, that samples data via one regular channel and result sended via DMA. This DMA are working in Normal mode, so after DMA compete its transmission I processed received data and then enable ...
Hi,I'm using both ADC's on the STM32L412KB, code is generated used the STM32 Cude with Low Level Drivers.ADC1 works as expected, but ADC2 always reads 0, no matter in which configuration. So I'm assuming it's not a hardware fault, but a configuration...
