Posted on December 29, 2015 at 03:33I am using the STM32F072RBT6 64pin LQFP My code seems quite stable, but this chip is showing signs of being overly sensitive to temperature... Since I have so much capacitance around the board on the same power l...
Posted on December 17, 2016 at 19:28Hi,I would like to know if I can use one I2C bus for 3 devices, first is master, sencond is slave and third is master/slave (STM will siwtch between master and slave mode to communicate with this 2 devices). Is th...
Posted on December 16, 2016 at 14:08Hi,My name is amarr., am new to this forum, I am trying to send some AT commands to STM32F401VDT controller throughSPI protocol to Wifi module(ESP12E vendor Ai-Thinker). For that purpose i need to make Module into...
Posted on December 15, 2016 at 14:11Hello, I'm trying to work with USB FS mode embedded in stm32f407vgt6 as device connected to PC(host), the reference manual says FS mode supports 12MHz speed and it's mentioned in the notes of CDC library (version ...
Posted on December 15, 2016 at 22:59I have a STM32L152 device which spends most of its time in STOP mode, waking perhaps once an hour. I'd like to add IWDG support, but need to 'freeze' the IWDG during STOP mode, which per STM docs can be done.I hav...
Posted on November 28, 2016 at 17:27Hi,I am a newbie developer on stm32 and iar.I have a simple question about spi DMA. I use a stm32f412 mcu as a SPI slave device,when the DMA controller on the stm32 mcu is starting to move data from tx buffer to s...
Posted on December 16, 2016 at 13:26Hello,I am trying to erase a flash page in Bank 2 of STM32L071RZ and it instead erases the 1st page of Bank 1( where interrupt vector table is stored). The code is fine as the same works very well when the page ad...
Posted on December 15, 2016 at 23:38Just wanted to mention a small bug in CubeMX 4.18.0. I am using STM32F446ZET. It has two I2S peripherals. When I configure I2S1 in the Pinout tab, the Clock tab shows the clocks wired for I2S2. And vice versa. The...
Posted on September 27, 2016 at 00:44Hello everybody,I'd like upload and test an app on this board stm32l controller called BlueNRG-MS Beacon demonstration application supported by this evaluation board. So far I was not able to do this neither by f...
Posted on December 11, 2016 at 14:18Hi, friends.I try to link application sample from STMF1cube / STemWin with Keil uVision5 for evaluation board STM3210E_EVAL. I have 14 times 34 warnings about macros redefinition between ....\KeiluVision5\ARM\PACK...
