<p>Hello,</p><p>I am a new use to TTGO board with a display and also to MicroPython. I was trying to use custom font and used the online tool mentioned in the forum:</p><p>https://loboris.eu/forum/showthread.php?tid=826<br></p><p><br></p><p>I have generated the .c file and used the tft.compileFont() function to generate the .fon file. As I have used "debug=True", I could see the error as: </p><p><br></p><p>Error opening source file '/_#!#_spiffs/<file_name>.c'</p><p><br></p><p>Is it because I have kept the .c file at the wrong location? Where should I keep it?</p><p><br></p><p><br></p><p><br></p><p><br></p>

<p>Hi guys,</p><p>i would like to ask you for help.</p><p>I need to power <b>L</b><b>ilygo TTGO T8 V1.7 ESP32 </b>with 5V (step down convertor). Is it possible with 5V Pin? </p><p>We just used USB and 5V pin to power display so im not sure about 5V input or output...</p><p>Best version for us is to use step-down convertor 5V to power display and LilyGO at once.</p><p> I have backup setup with another step down convertor to simulate 4,2V battery and then 5V pin to power display again,but its actually shiping and looks stupid in my eyes...</p><p>thanks!</p><p><br></p><p>pinout:</p><p>https://cdn.tindiemedia.com/images/resize/UklVmED7sdKHsvyvZf7-feFSScU=/p/fit-in/1032x688/filters:fill(fff)/i/56359/products/2019-05-25T07%3A58%3A22.171Z-T81.7.jpg?1606306133<br></p><p><br></p><p>schematics:</p><p>https://github.com/LilyGO/TTGO-T8-ESP32/blob/master/t8_v1.7.1.pdf<br></p>

<p style="margin: 0px; padding: 0px; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 14px; color: rgb(51, 51, 51); caret-color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none;">I have been a user of the Lobo ESP-32 Micropython fork for quite some time and have implemented several significant projects in it with great success. I have worked around the few serious bugs and find that the advantages of this fork to greatly outweigh the disadvantages of working with a semi-dormant fork. I have been a happy user.</p><p style="margin: 0px; padding: 0px; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 14px; color: rgb(51, 51, 51); caret-color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none;"><br></p><p style="margin: 0px; padding: 0px; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 14px; color: rgb(51, 51, 51); caret-color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none;">However, I now have an imminent need for Bluetooth support, and so am faced with a decision point. The current (2018) release contains a BT module, but the release notes say that it is experimental and should not be used. So, I have a decision to make. Should I:<br><br>1) Ignore the warning and lack of documentation and attempt to use the existing BT library?<br>2) Find another Micropython BT package and attempt to import it?<br>3) Abandon this port for another fork?<br><br>I hate the thought of #3, since I like the current one a lot and have a lot invested in it. It is my understanding that there is a newer version that is used for the K210 project. <span style="caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; display: inline !important; float: none;">Is there any way I can use this version in an ESP32-only project?<br></span><br>I realize that a new ESP release has been in the works for a while now, but I have run out of time.<br><br>Has anybody found a practical way to use BT with the current library?<br><br>Any information or advice would be appreciated.<br><br>Thanks for any help.<br><br></p><br><p></p>
