Greetings Friends.I want to interface proximity sensor with STM32F030R8T6 for measurement of RPM. I need guidance on how to make it possible and easy with out the use of PLL ic .I was thinking of interfacing proxy sensor output to STM32 pin and take ...
We are using the STM32F091RC to setup an RS-485 interface with the TI SN65HVD11. How do we connect to the DE control signal for the SN65HVD11? I have currently selected USART3 -R - PC5 (RX)D - PC4 (TX)DE - PB1 (RTS) Is this correct? Also what is CK_R...
I am using cubemx generated SD card test code on a custom board. And everything looks fine in SD 1bit mode, I can create new file, read and write data to it correctly. But when I am using 4bit mode, the f_open() function stalls. What might be the pro...
According to RM0433 revision 5 section 7.5.12, “The AXI bridge clock is enabled when the CPU is in CRun mode.�? Does this mean that the AXI bridge clock is disabled (and presumably things connected to the AXI, like the MDMA) do not work in CSleep? Th...
I would like to know what are the possible ways to save 40KBytes per second? what type of memory devices do i have to use. I presumed of using class 10 memory card but it has only 10Mbitspersecond (= 1250KBytes/second). I would have to store atleast...
So I have two timers, one in OC mode and one in IC mode. The IC waits until the OC toggles, it registers the value and waits for it toggle again to record a second value. What I want to do is after the OC timer has toggled twice is for it to disable ...
Hi,Is there any utility to upload .hex file image for STM32F407 MCU?Thx****
Posted on January 26, 2018 at 18:50Hi,I have a problem with the PLLSRC of a STM32F030RC : to obtain 24MHz for the sysclk I have to use PLLMUL @ x6 with HSI (8MHz) but 6x8 = 48MHz ?If I output the sysclk on a MCO pin (with no div) I have actually 24M...
HiI have learned AVR with C language . I have learned C++ language and a little C# .Now i want to learn stm32 . I have 2 questions .1.What should i do ?2.Should I read the reference manual first or the Hal driver?
How to start the RTC (real time clock) in the STM32F2xx processor with a 25 Mhz OSC
