Checked the Max Build for ESP32

Summarize of the problem/feature request

I have a Buttonboard that is using a PCF8575. The PCF8575 is not supported yet. Please add support for that I/O Expander.

Expected behavior

Supports 16 I/Os

Actual behavior

If i select PCF8574 (that one is recognized via I2C Scan even the bigger PCF8575 is build in) i get I/O Signal from PCF8575: 0x20 P0 from P00 0x20 P1 from P01 0x20 P2 from P02 0x20 P3 from P03 0x20 P4 from P04 0x20 P5 from P05 0x20 P6 from P06

P7 seems not to work.

i also get online response from espeasy at 0x3c (60) from P0 to P7 but no answer if i trigger ports of the PCF8575

Steps to reproduce

Expand the Plugin P019 within P8-P17 or
Create a total new for the PCF8575

yes

System configuration

Hardware: Used a ESP32-WROVER-B and a so called button baord from NERDIY.de https://nerdiy.de/en/buttonboard/

Have you tried the same test using the MCP23017 plugin, that does support 16 pins, and looks to be quite similar in software-interface?

Cover1987 commented 2 years ago

MCP23017 Test: 0x20 PA0 nothing PA1 nothing PA2 siganl from P01 PA3 siganl from P03 PA4 - PA7 nothing PB0 signal prom P00 PB1 nothing PB2 signal from P02 PB3 signal from P03 PB4-PB7 nothing

all other ports from other I2C Adresses are showen as offline

This could be partially solved (input only) via #3927

@Cover1987 the mentioned PR has been merged, does that help enough to close this issue?

I've updated to the newest build but cant find the Keypad with the PCF8575. ESP_Easy_mega_20220427_test_E_ESP32_4M316k Apr 27 2022 (i tried all Tests) Can only find the MCP23017 (9x8 and direct 16) and PCF8574 (5x4 and dircet 8)

For the PCF8575 you will need a build that doesn't have LIMIT_BUILD_SIZE (compile-time option) set, and all TEST builds have that enabled... You can optionally create a Custom build yourself (the standard Custom builds don't include this plugin), or... I'll create a TEST_E build (or do you need some other specific plugin/build?), that does include the PCF8575, later today. Still at work...

tonhuisman commented 2 years ago

Oh, one possible other solution is to use an ESP32 with 16 MB flash, then you can install a MAX build, that includes all plugins and has all compile-time-optional features enabled.

Cover1987 commented 2 years ago

I've only the 4MB Version. I'll give it a try tonight to compile it by myself. If i don't have success i'll come back to you <3

FYI: ESPEasy development starter guide (and on the same page is the info for setting up VSCode)

Cover1987 commented 2 years ago

ehmm.. nope - i didnt get it working. If You could compile it for me, i would be gratfull. If possible with P019, P036, P045, P037. Thank you!

tonhuisman commented 2 years ago

Here is a Custom build (based on the regular Custom configurations, with some plugins added)

ESP_Easy_mega_20220515_custom_ESP32_4M316k.zip

NB: Support for PCF8575 is only added to the Keypad plugin (P061), and not to the Switch input - PCF8574! (P019) The other plugins you requested are also enabled in this build.

Thaks a lot. I could flash it with out problems. But i don't get most of the inputs to work,

If I select 9x8 Matrix i get following output from the logging:

23197: Webserver args: 0: 'index' length: 1 1: 'page' length: 1 25675: Webserver args: 0: 'index' length: 1 1: 'page' length: 1 2: 'TDNUM' length: 2 3: 'TDN' length: 8 4: 'TDE' length: 2 5: 'i2c_ad 25679: SaveToFile: free stack: 6712 25812: FILE : Saved config.dat offset: 32768 size: 520 25813: SaveToFile: free stack after: 6712 25879: SaveToFile: free stack: 7080 26002: FILE : Saved config.dat offset: 32768 size: 520 26003: SaveToFile: free stack after: 7080 26052: SaveToFile: free stack: 7160 26560: FILE : Saved config.dat offset: 0 size: 3004 26560: SaveToFile: free stack after: 7160 26573: SaveToFile: free stack: 6600 26583: FILE : Saved security.dat offset: 1024 size: 128 26584: SaveToFile: free stack after: 6600 27123: KPad : ScanCode=0x0

After that i get feedback by pushing buttons from: P00-P07 (Pin4-11) no feedback. P10 (Pin13) "KPad : ScanCode=0x1" P11 (Pin14) and P12 (Pin15) "KPad : ScanCode=0x2" on both P13 (Pin16) "KPad : ScanCode=0x4" and 0x0 if i release the button.

P14-P17 i dont use in my project.

Are pull-up resistors connected on all inputs of the PCF8575, as stated in the documentation? As this chip does not have them internally, unlike the PCF8574 which has these internal pull-ups.

Yes, every single input has its own pull up resistor
