STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
please review the datasheet,--4 Pinouts and pin descriptions-- from the datasheet, both PIN 42/43 and 45/46 could be I2C1; both PIN 21/22 and 35/36 could be I2C2; which is right exactly?
Hello,I am measuring execution time of a function that operates with floating point numbers and noticed that it is more than I expect. I am using Nucleo F429ZI, clock is configured to the 50 MHz. For measuring the execution time I use TIM6 configured...
Are there pictures of microarchitectures of STM32F4 series devices? Something like this picture of 56301 DSP.http://strategysanity.com/s-images/dieDSP-Motorola56301.JPGWe'd like to find out what killed some processors on our boards. The dead processo...
Hi! I'm working in a bypass analog signal to external DAC and I did this isolating and checking (if H or L) each bit from adc buffer to load each 12 GPIOs. I'm looking for other soluton to do this. Can someone suggest other solution?
I wonder if there is some known issue?With logic analyzer I confirmed that I had extra clock pulses in the SPI after the data was read.The chip is STM32F427@180MHz.PCLK2 is 90 MHzSPI4 (master) is used with 16 bits and with prescaler 64, half duplex, ...
Is there a way to enforce a coding standard in STMIDE with some text highlighting?i.e: "function names should be Function_Name()" etc. What rules does STM use for their generated libraries in this case? Does anyone recommend some plugins for this? Wh...
Hi.I am working with a mcu stm32f030k6.My problem is that I can not protect my memory reading.I used a few code samples but got no results.Is there a solution?Using with writing code of the the main mcu or This can be done through the programmer J-li...
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...
