Hi,Currently I am working on a stm32 & LTC4015 based smart charger project. When I followed the data sheet the smbus or i2c read & write operation is given as below:-SMBus WRITE WORD PROTOCOL:-S SLAVE ADDRESS Wr A COMMAND CODE A DATA BYTE LOW A DATA...
I am using SPI 1 on a pair of Nucleo-G474RE boards that are running the same software image. On of the interfaces is working correctly, the other is not. A logic analyser shows the following: Working Not working From this, it looks as if there is a...
Hi currently I am implementing a smart battery charger using stm32 & ltc4015.But i could not understand how to perfectly configure ltc4015 through i2c protocol.So could you please inform me how to write the i2c sequences to safely charge the battery....
STM32H5x3 / VQFN68 packageHas USART3 but AN2606 lists using PD8/PD9 that this package does not have.AN2606 has a lot of remapping mentions for specific packages. Is this one of them, or does USART3 and bootloader not work for this package?
Hello everyone,I am unable to understand how to get one pulse . Tried methods from online but cannot get any result. I only see a sine pulse from the terminals in oscilloscope.I would like to give a pulse of 15 V and 3A for 50 micro seconds to my 3 p...
Hello,we use a STM32G483RE for analog sampling of downconverted RF signals. To maximize the signal-to-noise ratio in the digital domain we use one of the OPAMPs in inverting PGA mode with a voltage offset that is fed by a differential to single-ended...
I'm using a 32F469IDISCOVERY board (Cortex-M4). The integrated ST-Link V2-1 has firmware V2J37M27 and is configured as "Debug + Mass storage + VCP Modus" (default). It doesn't look like it has a jumper or solder bridge to connect SWO and I think it's...
Hello, I need the PF2-NRST pin on the STM32G0C1 chip as an MCO. Thus, I had to change the user flash to use the pin in GPIO mode. While I had doubts about this approach's validity since we are fiddling with the NRST, I still went ahead with it. Now t...
i'm trying to read the G030 mcu (from my PCB) with cubeProgrammer and the results are:"No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication"Today the debug pins are direct connectio...
Hi,I'm using AzureRTOS on a STM32H743ZI. I have a low priority task that is sending data via UART every 100ms (115200 baud). I would like to send this data with HAL_UART_Transmit_DMA, but after calling this function, the program stucks in the functio...
