+    git clone https://github.com/Hermann-SW/RPI-Pico-Cam.git
+```
+## Compile rp2040_hm01b0_st7735 demo
+```bash
+    cd RPI-Pico-Cam/rp2040_hm01b0_st7735
+    mkdir build
+    cd build
+    cmake ..
+    cd build 
+    make 
+```
+## Copy the arducam_firmware.uf2 to pico
+```bash
+    cp arducam_firmware.uf2 /media/pi/RPI-RP2/
+```
+
+## Comments
+
+It turned out that "capture camera frame, then show on display" loop runs sqrt(2) times faster on core1 (higher processing framerate). In addition another factor 2 was achieved by going to the "safe" double frequency 250MHz overclocking. With that, now 15.6 frames per second get shown on 160x80 display.
