Re: On-Screen Battery Monitor Options

i know its been a while but i got a question/problem not sure if its the ADS1115 chip or not (since i have been through 3 of them now) but it seems that I2C connection is not being made to the SDA pin/ hole on the ADS1115 chip. when i run the command to see what it finds it is only saying it finds ...

Re: On-Screen Battery Monitor Options

Has HHBatteryMonitor.py been updated recently? I'm not seeing what to update for 16bit. Can someone tell me what should be updated? https://github.com/HoolyHoo/gbzbatterymonitor/blob/master/HHBatteryMonitor.py The script you want is in the minty pi folder on hoolyhoos github https://github.com/Hool...

Re: BW screen not found on wiki.Help!!!!

So I just got this same screen/board and I'm having an issue. Removed the RZC2013S chip, soldered 5V to pin 3 and all I get is an occasional flicker of the backlight. I also tried running a jumper wire from pin 3 back to the original +12V point in case there was something else that required power p...

Re: BW screen not found on wiki.Help!!!!

Also the other chip is just a spi memory chip. You soldered 5v to the serial out pin, which I wouldn't expect to hurt it but I guess its possible. On the rzc2013 you soldered the 5v to the voltage input so I don't think you really changed anything by doing that because powering it by 5v with zero mo...

Re: BW screen not found on wiki.Help!!!!

Hi joey, and many, many thanks for your help. I Just checked the numbers on the two chips, but I found no XL1509, I have: the one on the right: RZC2013S the one ont he left: T25S40 I find these specifications on the Internet: RZC2013S: http://img009.hc360.cn/m8/M07/AA/BB/wKhQpVYt9feENd_8AAAAAHR4jTI...

Re: BW screen not found on wiki.Help!!!!

Check theses guys here: https://imgur.com/a/mT4gB You are looking for the IC 1509, the DC to DC converter is the one you are looking for. The datasheet for it is: www.xlsemi.com/datasheet/XL1509 datasheet.pdf Just check with some loupe or magnifier glass to check the pinout. Counting from the smal ...

Woops I mean .7v. not .5 but still same concept. Should allow the range of the battery voltage for a0 without the need of a voltage divider and still provide enough power for the module

Re: On-Screen Battery Monitor Options

Continuing the conversation from the other thread... While it my not be an ideal situation, it seems like just powering the module from 5v without removing any pull-ups should work fine. The raspberry has 1.8k ohm pull-up resistors to 3v3 on the sda and scl lines on board. The module has 10k pull-up...

Re: Veteran's 3rd "THE ULTIMATE CUSTOM BUILD"

If that is the case, then I would recommend to those reading to creat a voltage divider with a 10k and 5k resistor pair. Use the 5v source and the output will be a rough 3.3v , falling within spec ;) hopefully this can help someone out I'm not sure if it will cause damage to the pi but you are only...

Re: Veteran's 3rd "THE ULTIMATE CUSTOM BUILD"

Hey one thing i realized is that on the ads1115 boards they have pull-up resistors on the sda and scl lines so if you power the module from 5v these lines will have the pi's pull-ups to 3v3 and also the modules to 5v. Not sure how this might affect things but might be a good idea to cut those traces...
