This is an adaptation of the excellent general purpose VFO software by Nick Kennedy, WA5BDU. This can be used as part of a homebrew SDR rig or to support experiments in the workshop. …
A simple VFO for the Si5351 for either LCD, LCDI2C or OLED
2020年12月26日 · VFO will NOT tune in TX. LCD connections for for the LinkSprite 16 X 2 LCD Keypad Shield for Arduino. Change as necessary for your LCD. volatile unsigned long frequency = 7100000UL; // This will be the frequency it always starts on. unsigned long iffreq = 0; // set the IF frequency in Hz.
初学做VFO学用SI5351和8051请老师们指点 - HamCQ 社区
1, 49S,49U晶振不要用,太费劲,难调,个人建议直接使用TCXO价格也不贵。 2,用8051这种系列的入门容易资料号,要做个这也是有点些,建议用Arduino Nono这个就好,入门更快,现成的代码也多,搞搞逻辑,明白原理很快可以做出到,像我这个搞了2年,唉,中间也是有几次想放弃。 3,介绍一下上面板子的大概情况: 1) MCU: STC8G1K17A, SOP8. 2) SI5351A. 3) EC11很常见的编码器. 4) OLED I2C屏,中间字体手绘,现成的没有这个费了老大的劲. 暂时这么多, …

基于 VS Code 搭建 C51 单片机开发环境 - CSDN博客
2024年12月25日 · 一次在使用 VS Code 开发 ESP 单片机时,无意发现了 VS Code 也可以开发 C51 单片机,只要安装了 EIDE 插件,连 STM8、STM32 等单片机都可以在 VS Code 上开发。 EIDE(全称 Embedded IDE)是国内开发的 VS Code 插件,经过一段时间的体验,比 Keil 好太多 …
Now a “synthesised VFO” can be built with two cheap chips. A Si5351 programmable clock chip & a microprocessor. Introducing the Si5351: This chip is a programmable clock generator, intended for digital applications. It offers modest performance in the way of timing jitter (which leads to spurious birdies & FM), but turns out to be
