Re: How to use PSRAM for static definitions and malloc()? Postbyshabtronic»Sat Dec 21, 2019 1:54 pm I think you can only use the EXT_RAM_ATTR on zero'd var's. I think the reason is - the system would have to copy the init data to spiram - making it more complex under th...
ESP32支持与SPI Flash芯片并联的SPI PSRAM,ESP32接口可以支持多种类型的RAM芯片,但是IDF仅支持ESP-PSRAM芯片 ESP-PSRAM32 芯片的工作电压为 1.8 V,只能与 1.8 V flash 并联使用。请确保在启动时将 MTDI 管脚设置为高电平,或者将 ESP32 中的熔丝设置为始终使用 1.8 V 的 VDD_SIO 电平,否则有可能会损坏 PSRAM...

Currently my receiving rxqueue size is 70000. so we add to PSRAM memory. Here how to link the rxqueue to PSRAM memory. Is there anyway to use PSRAM instead for rxqueue? Kindly provide me some guidelines to solve this problem , to move further steps in my project . ...
If to move from WROOM TO WROVER B, is it possible to use PSRAM for this purpose at Arduino IDE? If YES, how to connect PSRAM and how slower it will be work? Thanks! P.S. May I use pins for SDMMC and vspi? SDMMC ESP32 D2 12 D3 13 CMD 15 CLK 14 D0 2 D1 4 vspi SCLK...
Description: How to use psRam for wifi (ssl) and BLE in Arduino ide? Just turning on the psram does not do anything because you need to use ps_malloc () to use external memory, how can I fix this? My board ESP32-WROVERContributor beegee-tokyo commented Oct 1, 2018 Not sure about...

When WROVER module (instead of the default WROOM) is used then GPIO16 and GPIO17 are unavailable (both are used for the PSRAM inside the module). In that case we have set GPIO33 to go on UEXT1 pin #5 (instead of GPIO16). Also the clock for the Ethernet is now GPIO0 (instead ...
not enough internal RAM to have double frame buffer for 320x240 in 16-bit color, it limited the multitask design. It can overcome a bit with external PSRAM though it is slower than internal RAM not enough processing power to decode mp4 video ...
