Posted on June 13, 2016 at 18:50Hi.I communicate between two F303 parts over UART. Both modules are clocked with 72 MHz. USART1 on one part is on APB2, which runs at 72 MHz. On the other part, USART2 is used, which is on APB1 (36 MHz). But USART2 is...
Posted on June 08, 2016 at 11:32 Hi, I have a problem with CAN after a bus-off condition. When CAN state changes to bus-off, I set the CAN operation mode to SLEEP mode. After a few 100 ms I try to bring the CAN bus into NORMAL mo...
Posted on June 10, 2016 at 13:01 I found a blocking delay function on the Internet (http://thehackerworkshop.com/?p=1209 ) and I made some small changes to it: void delay(Delay_t delay_) { unsigned int loopsPerMicrosecond = (unsigned...
Posted on June 13, 2016 at 16:56This is in the http server example in the CubeMX firmware, V1.4.0 for F7.I'm modifying a web page from the original in the DynWebPage function which has a PAGE_START and a PAGE_BODY both specified at 512Bytes.I want t...
Posted on June 07, 2016 at 09:36Hi, are there any tutorials for getting an HTTP server working from cube firmware?I found the demo project in the F7 cube firmware V1.4.0 which displays which tasks are running on FreeRTOS. Works fine, great. Now I ...
Posted on June 13, 2016 at 14:36Hello,As i am designing a project for low power application. The best microcontroller that i had selected is STM32L053R8 which is cortex m0+. Now after drawing shematics according to my application requirement i found...
Posted on June 13, 2016 at 13:53No peripheral enabled.Only mcu is mounted and power is feed from power supply directly.Current is nearly 170 uA at MSI 1Mhz low power sleep mode.but cubeMx says 65 uA.In other modes, current is almost 100 uA more than...
Posted on November 11, 2015 at 06:04hi all, I am a newbie in STM32. Now I get an application to make STM32L476 as an USB audio device and playing music in PC will play in the speaker connected to STM32L476. I use the USB audio class(device) and win...
Posted on June 02, 2016 at 15:24Hi All,The device is being used STM32F746BGTX.Set as follows. FMC_NORSRAM_TimingTypeDef Timing; /** Perform the SRAM1 memory initialization sequence */ hsram1.Instance = FMC_NORSRAM_DEVICE; hsram1.Extended = FMC_...
Posted on May 31, 2016 at 16:28I am working with the Discovery Development Board and a custom-made PCB with an STM32F405 microcontroller operating at 1.85 Volts. I would like to be able to easily switch clock frequency, that is, I would like to have...
