Posted on January 26, 2013 at 19:19An Open Letter to ST Micro I'm switching my development projects from the STM32 to Microchip's MIPS-based PIC32. I'm a hobbyist, so my concerns may be different than the pros' here - and the impact of my decision o...
Posted on December 15, 2015 at 10:56Hello and thanks in advance.I have now a STM32F091 Nucleo. I am interested in running SPI on it. However by looking at the page of the product I can not tell which pins are for SPI or if it supports SPI at all. Fo...
Posted on December 15, 2015 at 14:35Hi I have seen that spi has 16 bit buffer but only we can send 8 bit. Would like to know why it is like that ?
Posted on December 15, 2015 at 13:41 I'm using STM32F411RE-Nucleo board and generating a project with Cube MX for System Workbench. The problem is that,HAL_UART_Receivefunction doesn't receive input from the user, even though I don't change any U...
Posted on December 10, 2015 at 22:29 Okay, we have a bootloader that we want to replace programmatically, as it is not practical to get access to the debug ports. I've done this successfully with a STM32F071, but have not been able to get it worki...
Posted on December 14, 2015 at 10:41Hi, We are using an ARM STM32L100RC. We receive in our firmware a message of just two characters through the USART 1. At 9600 kbps it works ok, at 19200 it fails sometimes, but at 38400 it fails one in ten times (...
Posted on December 15, 2015 at 14:55Hi everybodyI am trying to implement some mathmatic calculations in STM32F103.I use HSI and PLL to provide 64MHz and 36MHz clock, considering Flash Wait State and enabling Prefetch Buffer. I expect that the calcul...
Posted on December 12, 2015 at 16:29Hello All, Moving from the Motorolla 9s12 to the stm32. Just got a eval board and after recovering from Register shock I am just trying to get some blinky lights and serial comm (USART) going which is what I wou...
Posted on December 15, 2015 at 12:16Dear,In my STM32F429 application I use a mouse or a keyboard The USBH_HID_EventCallback is common to both It would fine to have a different callback registered in the HID_Handle by USBH_HID_InterfaceInit() like it...
Posted on December 15, 2015 at 10:05 I'm using STM32F4 Discovery. I configured a GPIO pin PB8 for external interupt for both rising and falling edges, so that I have to reset a flag when it is high->low or set when low->high which is done by rea...
