Hey guys, befor asking my question I want to give you a brief overview of the test case:TestCase: SPI Full DuplexMaster send [0-3](4) bytes and Slave returns received bytes [0-2](3) immediatly. (no register preload in slave)Example:Master <-> Slave0x...
I have encountered a strange power draw behavior of an STM32L0 device in a battery powered circuit. Using a Nordic power profiler kit, the device draws the nominal 5 uA current after entering Stop mode then seems to "wake-up" and draw 78 mA. The curr...
Hello, I want to implement an I2C slave on the Nucleo board with interrupt functionality. As a master, I have an Arduino ESP8266. The master queries data from the nucleo. Now I'm not so familiar with the STM32 and Nucelo and HAL. Is there a giagram o...
Posted on December 17, 2013 at 05:03Greetings all, I've been playing around with SDIO on an STM32F4 -Discovery card with the Embest Baseboard on it. My goal is to get it to work in polling mode, flow control mode, interrupt mode, and dma mode. This ...
Hey, I try to get timestamp from tamper event when mcu supplied with VBAT, but value oftimestamp still 0, can anyone help me ?
Posted on October 22, 2016 at 16:36Hello,I am having an issue with DFU downloading to a STM32L476 Discovery board.- Compiled a simple LED switching application in IAR converted to DFU by the file manager (tried both bin and hex)- Tested via ST-LINK ...
24 Timers This project could use 8 independent PWM outputs, plus 8 independent countersand another 8 wouldn't go unwanted. these would still offer IC and OC, PWM etc.
Posted on May 24, 2018 at 12:03I have designed a board using the STM32H743II. During integration testing of the software I have found the following issues related to the microcontroller (SCB->CPUID 0x411fc271) :1)SPI1 and ADC1 is not working when us...
Hi,I am having problems sending a part of an array with SPI. It is no problem to send 4 Bytes from the beginning of the array, but if I want to send 4 Bytes from another starting position (for example: start from tmp[1]) it does not work. In this cas...
Hey, I want asking something, I have a value on backup register, but when the tamper is active when power off, the value on my backup register was reset. On datashet get to protect the backup domain no erase or mask flag bit must enable. I set the no...
