In 2/1 duty cycle, fpclk shall be a multiple of 1.2MHz (400KHz*3). Under this assumption, I re-configured my clock source from HSI to PLL and change to SCL speed of Arduino to 400KHz. As shown in this image. STM32 Clock Configuration. New system clock and fpclk1 for 24MHz are configured. STM32 core support for Arduino.

Voltmeter click is a mikroBUS™ add-on board for measuring voltage in an external electric circuit. The board is designed to measure Direct Current only, and has a measurement range from 0 to 24V (it’s possible to measure both positive and negative charges). gpio_set_mode(gpioa,gpio_mode_output_50_mhz,gpio_cnf_output_altfn_pushpull,gpio_usart1_tx); 你可以看一下stm32总线框图,这些都是一些分频,提供给各个外设使用,具体的你看下资料吧 一言两语说不清楚.希望能帮助你. Hello Eric, Thanks for your reply & guidance. I've formatted the code & previewed.

调试stm32F103C8t6的SPI1遇到的问题和解决途径 - 这两天从F4单片机要把程序换到F1里面, 于是做了板,移植了程序(框架直接利用cube重新生成的)调试到SPI1读取ad7655的时候遇到点麻烦.按照F4的程序,想当然的复制黏贴之后,运行读出来的ad值乱七八糟,更可恶的是查看寄存器发现spi出现了OVR溢... A free/libre/open-source firmware library for various ARM Cortex-M3 microcontrollers.

Serial Peripheral Interface (SPI) Synchronous serial data transfers Multipoint serial communication between a “master” and a “slave” device Clock permits faster data rates than async communications (framing unnecessary) Signals = clock, data in/out, “slave select” Master controls data transfers: The simplest way to produce regular interrupts from a timer like TIM3 on the STM32 family of processors is to set up the Auto Reload Register (ARR) to generate an update event. This article shows you how to correctly set up the clock source, prescaler and ARR to get regular events over a wide range of frequencies. STM32 core support for Arduino.

Your fputc sends bytes directly to the UART, which goes to the RS232 connector on board. If you want to see the output of your fputc, you need to connect a cable between the board and the PC and see it with a client such as hyperterminal.

For example, if the SPI peripheral, that microcontroller is getting 50MHz of a peripheral clock, then the maximum speed of a peripheral clock is 25Mbps. Because the maximum speed of the peripheral clock is divided by 2 (fPCLK/2) as shown in Figure 1. Hence, SPI works over a shorter distance but at a higher data rate or higher speed.

The PLL gets fed by a 8 MHz HSE oscillator (STM32_PLLSRC = STM32_PLLSRC_HSE) that is first divided by STM32_PREDIV_VALUE = 1 and then multiplied by STM32_PLLMUL_VALUE = 6. This gives us a 48 MHz SYSCLK (max speed for the F030F4). HCLK is SYSCLK divided by STM32_HPRE_DIV1 = 1, therefore HCLK is 48 MHz.

Serial Peripheral Interface (SPI) Synchronous serial data transfers Multipoint serial communication between a “master” and a “slave” device Clock permits faster data rates than async communications (framing unnecessary) Signals = clock, data in/out, “slave select” Master controls data transfers:

* 8-bit data, master mode, full-duplex, clock is fpclk / 2 spi = ( struct spi_ctlr *) stm32_spi_addr ( SPI_PORT_HOST ); /* Enable rx DMA and get ready to receive our first transaction */

We have picked a 36-pin, 72 MHz STM32 (STM32F103T8U6), fast enough to generate monochrome video synchronism and dot signals. We use a couple of timers and the SPI (this way the refresh of the frame buffer is done automatically). And the final result is a pretty decent monochrome VGA output with 400 x 200 dots resolution.

SPI library routines require you to specify the module you want to use. To select the desired SPI module, simply change the letter x in the routine prototype for a number from 0 to 3. Number of SPI modules per MCU differs from chip to chip. Please, read the appropriate datasheet before utilizing this library.
