External Flash for RENESAS RA4M1
Hi , The RA4M1 does not accept external parallel buses. In order to add external memory to this device, for instance, you would need to use the IIC or SPI interfaces. Thanks
Hi ,
How can I adjust LEDs Brightness with Dimmer?
Hi dear , please help to share the more detail about this project and if it is possible please help to share your schematic because here one confusion how we can take 36 LED output from the dimmer ?? thanks

MQTT Starts Too Slow

hello,
It isn’t experiencing a “bottleneck” problem. I believe that every time his device reconnects to the wifi, there is a delay. The amount of time it takes to connect to wifi can vary depending on your proximity to the network and can take several seconds.
I experienced the same issue with remote sensors that required deep sleep in order to conserve battery. It was necessary for a sensor to re-connect to the network after an incident that caused it to awaken from deep slumber. The system as a whole was slowed down by the normalisation of connection time required for sensor synchronisation. Espressif’s ESP-Now is the answer it offers to this specific issue.

Issue in Capacitive Touch
On reflection, you are having an issue with tuning, The tuning process is part of QE and the tuning "code" is download TSCAP ( P1.12 on the RA2L1 MCU ) should be connected to ground via a 10nF capacitor. Have you enabled the TSCAP pin in the FSP pin configuration?

Hi
please share the which BMS IC part no those you are using and you can use BP semi IC BP5428 and this type issue never come
Abnormal charging protection
The battery voltage will continue to rise if the
overcharge protection fails. Once the battery voltage is
higher than 4.35V , the BP5428 will bypass the
charging path to protect the battery(K1 off, K3 on) .
Battery charging & Over-charging protection
• The battery is charged through LED1, Rch and K1(K1 on, K2
off). The charging current equals to ILED1.
• Once the lithium battery is overcharged, the battery voltage is
higher than 4.2V for more than 130ms, the chip will cut off the
charging path and the emergency LED2 is turned on(K1 off, K2
on). Only when the battery voltage drops to 4V, the charging
circuits operate again.
◆ Battery discharging & Over-discharging protection
• The battery is discharged through K1, Rch, LED2 and K2 (K1
on, K2 on) in emergency mode.
• When the lithium battery is over-discharged with the battery
voltage under 2.7V, the battery is stopped to discharge by
BP5428(K1 off, K2 off).
