Hi, welcom back again to my another blog post. Today I will take you through my second time trying to reverse engineering something after the MN15439A vfd. This time, It's the hardware reverse engineering that I've been waiting for almost 2 years to have a chance to do that. I mean, I have a chance … Continue reading Wacom EMR I2C : HACKED!
Hi, It's quite a while now, and it been ~1 year since I bought Lichee pi nano and tried to upgrade from 16M SPI-NOR flash to QSPI-NAND W25N01GV 128M flash, I f**ked around with U-boot for year to make it boot but I didn't until 10 days ago (from the time of writing). I can … Continue reading Lichee Pi Nano with W25N01GV support [Complete Guide]
For anyone who already own this display and having stm32 in-hand. I'm appreciate to get help from you testing the driver. Recently, I came across the display that I've been waiting to buy since last year. It's SHARP Memory Display. I first saw this on WaveShare AliExpress store and it was 128x128 pixels (iirc) up … Continue reading SHARP Memory LCD with STM32F3
ComeNCapture is a small project, Quick and Dirty logic analyzer based on STM8L mcu. I wrote a little code for this project. Using timer 4 interrupt for adjustable data sampling rate. By manipulating 2 variables, ARR and prescaler. By using USART and baud rate of 115200. With USART interrupt, I can control when to start … Continue reading New project : ComeNCapture
Chapter 1 : Beginning 6 years ago. I got the old CD car player made by SONY. It's CDX-GT700D and this CD car play having such a fascinating feature. That is the Graphical Display with the the Blue-ish like 488nm laser ! So I don't delay de-solder-ed that day. removing the display and thrown the … Continue reading Six years of finding the datasheet and pinout of the MN15439A
Month ago, I got some very rare LED bar graph from yoycart ( Chinese taobao agent) here. And this is some bit from datasheet with the Charlieplex-like connection of bi-color LED (green,Yellow) Now we have the diagram, It's time for the real thing up and running ! As again. No arduino this time, just bare metal … Continue reading LTL-7100M-HB : The super weird bi-color LED bar graph.
Hi guys, I've been working for several days, And now it working ! Originally, I plan to use (and should use) the 560uH inductor. but due to COVID-19 outbreak. It cause most of economy shipping companies to slow the process down. All of the parts arrived fine except the inductor (which is suppose to arrive … Continue reading Back-lit TI-82 is done !
Hello guys. After couple months of covid-19 lockdown, pandemic, etc... My projects had been delayed and no where to be finished. Including FlexWatch 0.1 ELmod82 <CPU load monitoring via i2c bus on PC monitor for pc running linux, haven't got the name yet 😅> But at lease, I have enough time to made some video … Continue reading COVID-19 affected all of my project
I've made some update to the stm8L template, The updates including USART is working ! with the example code !!! Also made the configurable USART speed in usart_init(); I added my new little library call "dev_id" for reading Device Unique ID (according to datasheet), as well as example code I also ported the TIM4 delay … Continue reading STM8L template updates!
Yesterday (2020/2/2) I received my Graphing calculator from Denmark , but that is not t he point. It's TI-82 calculator. The USER-FRIENDLIER TI-85. Although, the online world in 2020 still lack of the useful Information and modification, But I found on the ticalc and someone made the TI-link compatible cable (Black link compatible) and someone had … Continue reading TI-82 calculator !
