digilent pic32

Since December 15, my spare time has been tossing the PIC32MZ EC Starter Kit purchased at the end of 15. and successively wrote more than 10 essays documenting the course of my toss. Recently completed by the C language to achieve the PIC32 UART bootloader, the use of serial communication, suitable for Microchip PIC32MZ EC, the corresponding modification can also be applied to PIC32MX, PIC32MZ EF and so on. The Uart bootloader is compiled with XC32, a

Bit to the board when the hint of error, engaged in a night, finally succeeded! Write down the process and hope it will solve your problem.Searching the Internet for this problem, there is a solution seems useful (but I do not use it), https://paddydempster.wordpress.com/2008/04/08/ Using-xilinx-usb-cable-on-ubuntu-without-windvr/,http://rmdir.de/~michael/xilinx

The previous "UART explained" introduced the basic information of the UART, focusing on the signal of the UART. The article excerpt from this article focuses on the baud rate (Baud rates) related content, the higher the baud rate, the faster the transmission speed, but the actual use of the baud rate is higher the better, how much appropriate? The answer is given in the text below.Although the PIC32 is an elegant and powerful microcontroller, it doesn

Hands-on Tutorial for the Zedboard?This article is mainly about Zedboard hardware system construction, U-boot,linux-kernel transplant, Linaro file system porting. The files that need to be generated in the process are system.bit,fsbl.elf,u-boot.elf,devicetree.dtb,uimage (see Zimage and Uimage differences), Linaro file system (linaro.org can be downloaded).
