The H7 series is the latest high-performance ARM microprocessor product line, while STM32H750VBT6 is the most cost-effective product in the H7 product line. It has all the features of the H7 series, and the price is suitable, which is ideal for high performance embedded applications. Finishing 10 STM32H750 minimum system and circuit design classic on the Circuit City, to learn together.
1, STM32H750VBT6 + ESP8266
+ OV2640 program development board (pcb + routine)
The development board STM32H750VBT6 as the master, uses three SPI Flash, wherein two master as qspi Flash, can be used to store code and data.
A remaining code to save the master SPI Flash ITCM, the download program, the ITCM Codes to the SPI flash download algorithm
Master starts operation, flash will have the master copy of the data in the SPI Flash ITCM in the code, after the copy is complete, the master starts running code in ITCM achieve level read clock speeds.
As qspi that two SPI Flash can not write in the microcontroller operation, while the rest of the SPI Flash can be written, but be careful not to overwrite copied to that part of ITCM.
SPI Flash read clock frequency is used with the suffix W25q128JVSIQ version V is the maximum read clock frequency of up to 133MHz STM32H750VBT6 JVSIQ ultimately to 120MHz.
If qspi peripherals using a PLL clock, you can reach even higher frequencies.
Boards can add OV2560 24Pin of a camera.
On-board development EPS5266 EPS-12S to communicate with the master via SPI ESP8266, ESP8266 firmware will need to write another.
The process of downloading the program to the need to press in ESP8266 master reset hold, to avoid the influence Esp8266 master in download mode.
LCD board features a serial interface can be accessed ST7789 display.
Development board onboard a TF deck. Separately derived SWD debug port pin 1 and pin.
The remaining lead to the development board io pin.
2, based STM32H750 development board, can be used to assess learning and development
The H7 series is the latest high-performance ARM microprocessor product line, while STM32H750VBT6 is the most cost-effective product in the H7 product line. It has all the features H7 series, e.g. Cortex-M7 core, the main frequency of 400Mhz, 1MB allocated SRAM, 16K instruction and data caches. Zero wait 128KB Flash, etc., but the price is right, very suitable for high-performance embedded application development.
The board based STM32H750VBT6 core, can be used to assess learning and development H7 series microprocessor
On-board ST-Link V2.1, debugging, serial port, U disk to download triple.
