I am doing some redesign work on a DIY 10 kW EV battery charger that uses an Arduino as its core processor, and I was able to extract the code in Hex format using an AVR Dragon. But I wanted to be able to read the text that is part of the code, used on the display, and I found it very difficult to find an application that does this adequately. I wound up importing the hex file into a Mic...

I have to use a lot of TFT LCDs like this: www.ebay.com/itm/2-4-inch-TFT-LCD-module-320x240-R61505V-touchpad-arduino-AVR-STM32-ILI9320-/121 033845957 I would prefer to use an automatic process to solder the flat cable, but the manufacturer said it is for manual soldering!! Is it true? Isn't there an automatic procedure to solder and mount this display?

Anyone implemented a coloumb counting algorithm on a uP before for estimating LiPo battery SOC? I'm powering an 8 bit AVR and a few external widgets off a small 3.7 volt single-cell LiPo battery, about the size of a stick of gum, and would like to give it a rough estimate of the battery's SOC without using more hardware. I have at least one 10 bit ADC channel available for sensing. Fo...


Does a diode in the Vcc line disable clamp diodes to Vcc

I have a case where I want to put about 20 microamps into an AVR at 12v. AVRs have clamp diodes to both ground and Vcc on their digital inputs. It seems to me that a diode inline with the Vcc supply would disable the internal clamp diodes of the chip. Am I correct on this or is the internal circuitry fancier than a simple clamp diode. Thanks, Bill

sci.electronics.design Atmel 328 external interupts I'm debugging an Atmel AVR 328 that won't generate an external #0 interupt. At present, the timer1 is generating an overflow interupt as would be expected. The input for the #0 ext. interupt (pin 4, d port #2) has been set to generate a mimic signal on another pin, which worked well. The setup for interupt 0 is: ldi areg, 2 ; ex...
